Introduction

The Z-Xtreme GPS receiver, Figure 1.1, presents a powerful and economical
alternative to conventional surveying equipment for the GPS community. Designed to
support an expanding variety of surveying applications, including land/boundary/
cadastral surveys, route surveys, construction, and as-built surveys, the 12-channel,
dual-frequency receiver integrates technological advances in microprocessor design,
data storage, and power management. Retaining the functionality of a complete
surveying system, the Z-Xtreme fits into an improved, lighter, and more ergonomic
enclosure. Incorporating Ashtech's patented Z-Tracking technology to mitigate the
effects of Anti-Spoofing (AS), the Z-Xtreme provides increased tracking ability under
adverse satellite visibility conditions such as under tree canopy, in canyons, or
between buildings.

The Z-Xtreme operates on just 6 watts and includes an internal battery capable of 10
hours of continuous operation. For longer operations, the Z-Xtreme offers an external
power input. The receiver also includes internal memory in the form of a removable
standard 16Mb PCMCIA card expandable up to 85 Mb. Due to performance and
popularity, many third-party application software companies have developed their
